Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production technology, and in particular to a cutting device for copper terminals of high-voltage cable connectors. Background Technology
[0002] When erecting high-voltage lines, copper terminals need to be installed at their ends to ensure a stable connection between the high-voltage lines and electrical equipment. Currently, copper terminals are mostly made by cold extrusion molding. The mold used to extrude copper can produce two connected copper terminals at once, improving the production efficiency of copper terminals.
[0003] A high-voltage cable multiphase connector disclosed in the existing publication (announcement) number CN203288817U includes a terminal connecting wire and a housing. The sealed connection between the terminal connecting wire and the housing is achieved by the engagement of the inner liner and the snap fastener on the flange 23. The other end of the terminal connecting wire is connected to a copper terminal, and the free end of the copper terminal is a copper plate with a centrally located circular hole.
[0004] One end of the copper terminal is tubular, and the other end is asymmetrically sheet-like with a round hole in the middle. After extrusion molding, the copper terminals are connected in pairs, with the connected end being the one with the round hole. At this point, workers need to operate cutting equipment to separate the two connected copper terminals. After separation, the sheet-like end of each copper terminal needs to be chamfered and a hole made, which affects the production efficiency of the copper terminals. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a high-voltage cable connector copper terminal cutting equipment, which solves the technical problem that after cutting the integrated copper terminals, it is still necessary to perform additional processing steps on each copper terminal, resulting in low production efficiency.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:
[0009] This utility model provides a high-voltage cable connector copper terminal cutting device, including a cutting assembly for cutting the middle of a continuous copper terminal and a conveying assembly for conveying the continuous copper terminal to the cutting assembly. The cutting assembly includes a horizontally arranged lower die base and a vertically reciprocating upper die base. The upper end face of the lower die base has a cutting groove for embedding the continuous copper terminal. The lower end face of the upper die base has a cutting head that moves synchronously with the upper die base and punches and cuts the continuous copper terminal. The two ends of the cutting head form chamfered cutting grooves on both sides of the copper terminal. The upper die base has a punch for punching and forming holes in the copper terminal on the side where the two cutting grooves are far apart.
[0010] This utility model provides a high-voltage cable connector copper terminal cutting device. When cutting integrated copper terminals, the integrated copper terminals are sequentially conveyed to the cutting assembly via a conveying component. The integrated copper terminals are embedded in the cutting grooves. Subsequently, the upper die moves vertically downward. Upon contact with the integrated copper terminals, the cutting head directly separates the integrated copper terminals. At the same time, the cutting grooves on both sides of the cutting head cut the integrated copper terminals to form chamfers. In addition, the punch moves downward simultaneously, punching holes in the copper terminals, thereby quickly completing the cutting and shaping of the integrated copper terminals. The copper terminals cut by this device can reduce subsequent processing steps, making it more convenient and efficient.
[0011] Optionally, the upper end of the lower mold base is provided with a feeding groove on each side of the cutting slot, and the cut copper terminal slides out of the cutting assembly along the feeding groove.
[0012] By opening two feeding grooves at the upper end of the lower mold base, the separated copper terminals will slide out along the feeding grooves after the integral copper terminals are cut, making it easier to collect the copper terminals.
[0013] Optionally, the lower die base is vertically provided with a support punch tube coaxially symmetrical to the punch column on the side of the material feeding groove near the cutting slot. The punch column moves with the upper die base and slides coaxially through the support punch tube.
[0014] By vertically setting a support punch tube on the lower die base, the integrated copper terminal can be supported, making the punching process smoother and reducing the deformation of the copper terminal. On the other hand, the waste generated during the punching process can also fall out along the lower opening of the support punch tube, avoiding the accumulation of waste and facilitating continuous operation.
[0015] Optionally, a separation mesh frame is provided on both sides of the lower mold base below the lower opening of the feeding chute, and the separation mesh frame separates and screens copper terminals and copper terminal opening waste.
[0016] By setting separation mesh frames on both sides of the lower die base, the copper terminals and the waste generated from punching will fall into the separation mesh frames. The separation mesh frames can screen the copper terminals and the waste generated from punching, which makes it easier to remove the copper terminals later.
[0017] Optionally, the conveying assembly includes a feeding slide and a baffle plate disposed on the feeding slide. The feeding slide is disposed on the lower mold base along a direction perpendicular to the length of the cutting groove. The feeding slide is inclined and allows the integrated copper terminals to slide down sequentially. The lowest end of the feeding slide is connected to the cutting groove. The baffle plate slides vertically and is connected to the bottom wall of the feeding slide at one end connected to the cutting groove, thereby intercepting the integrated copper terminals.
[0018] By tilting the feeding slide on the lower mold base, the integrated copper terminals slide down the feeding slide in sequence and are intercepted by the baffle, so that the integrated copper terminals can fall into the cutting slot in sequence, thus facilitating continuous cutting.
[0019] Optionally, the baffle is provided in two sets, and the two sets of baffles are distributed at intervals along the opening direction of the feeding slide, forming a gap between the two sets of baffles for a set of integrated copper terminals to stay in.
[0020] By setting the baffles in two sets, a gap is formed between the two sets of baffles that allows only one set of integrated copper terminals to stay. This ensures that only one set of integrated copper terminals is allowed to slide into the cutting slot each time the material is loaded, avoiding cutting errors caused by excess integrated copper terminals sliding in and improving cutting quality.
[0021] Optionally, the lower die base has a waste material slide on the side wall of the cutting slot away from the feeding slide. The waste material slide is inclined and connected to one side of the lower die base. The waste material cut by the cutting head slides into the waste material slide under the pressure of the next set of integrated copper terminals.
[0022] By opening a scrap chute on the cutting and slotting side wall of the lower die base, the scrap generated when the cutting head cuts the integrated copper terminal will slide directly into the scrap chute under the pressure of a new set of integrated copper terminals. This makes it easier to automatically clean up the scrap after each stamping and cutting, thereby improving production efficiency.
[0023] Optionally, the upper die base is provided with two sets of driving cylinders for driving the vertical movement of the punch, and the peripheral end of the punch is provided with grinding texture. The punch slides into the supporting punch tube and grinds the inner wall of the opening of the copper terminal.
[0024] The punch is driven vertically by a hydraulic cylinder, which causes the punching and cutting of the cutting head to be asynchronous. After the integrated copper terminal slides into the cutting slot, it is punched first and then cut. This allows the formed copper terminal to automatically slide from the support punch into the unloading chute, which is more convenient. At the same time, grinding texture is set on the periphery of the punch, so that the inner wall of the hole can be ground to a certain extent after the punch is punched. This reduces the subsequent processing steps of the copper terminal, making it more convenient, and also reduces the impact of the punch retraction process on the copper terminal.
[0025] (III) Beneficial Effects
[0026] The beneficial effects of this utility model are as follows: When the high-voltage cable connector copper terminal cutting equipment of this utility model cuts the integrated copper terminal, the integrated copper terminal is sequentially conveyed to the cutting component through the conveying component. The integrated copper terminal is embedded in the cutting groove. Then the upper mold base moves vertically downward. After contacting the integrated copper terminal, the cutting head directly separates the integrated copper terminal. At the same time, the cutting grooves on both sides of the cutting head cut the integrated copper terminal to form a chamfer. In addition, the punch moves downward simultaneously, and punches holes in the copper terminal, thereby quickly completing the cutting and forming of the integrated copper terminal. The copper terminal cut by this cutting equipment can reduce subsequent processing steps, making it more convenient and efficient. Attached Figure Description

[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] The high-voltage cable connector copper terminal cutting device proposed in this embodiment of the invention, when cutting integrated copper terminals, sequentially conveys the integrated copper terminals to the cutting component via a conveying assembly. The integrated copper terminals are embedded in the cutting grooves, and then the upper die moves vertically downward. After contacting the integrated copper terminals, the cutting head directly separates the integrated copper terminals. At the same time, the cutting grooves on both sides of the cutting head cut the integrated copper terminals to form chamfers. In addition, the punch moves downward simultaneously, thereby punching holes in the copper terminals, thus quickly completing the cutting and shaping of the integrated copper terminals. The copper terminals cut by this device can reduce subsequent processing steps, making it more convenient and efficient.
[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0037] Reference Figure 1 and Figure 2 A high-voltage cable connector copper terminal cutting device includes a cutting component 1 for cutting the middle of the integral copper terminal and a conveying component 2 for conveying the integral copper terminal to the cutting component 1.
[0038] See Figure 2 and Figure 3 The cutting assembly 1 includes a horizontally arranged lower die base 11 and an upper die base 12 fixed on the stamping machine and vertically reciprocatingly sliding on the upper side of the lower die base 11. The middle of the upper end face of the lower die base 11 is provided with a cutting slot 111 for embedding the integrated copper terminal. The middle of the lower end face of the upper die base 12 is fixed with bolts to a cutting head 121 that moves synchronously with the upper die base 12 and punches and cuts the integrated copper terminal. The two ends of the cutting head 121 form cutting grooves 122 that chamfer the copper terminal. The upper die base 12 has a vertically arranged punch 123 for punching and forming the opening of the copper terminal on the side where the two cutting grooves 122 are far apart. Subsequently, the upper mold base 12 moves vertically downward. After contacting the integrated copper terminal, the cutting head 121 directly separates the integrated copper terminal. At the same time, the cutting grooves 122 on both sides of the cutting head 121 cut the integrated copper terminal to form a chamfer. In addition, the punch 123 moves downward simultaneously and punches holes in the copper terminal, thereby quickly completing the cutting and forming of the integrated copper terminal.
[0039] See Figure 4 and Figure 5 The upper end of the lower mold base 11 is provided with a feeding groove 112 on both sides of the cutting groove 111. The cut copper terminal slides out along the feeding groove 112, which facilitates the collection of the copper terminal.
[0040] The lower die base 11 is vertically suspended by bolts on the side of the material feeding groove 112 near the cutting slot 111, and a support punch tube 113 is coaxially symmetrical with the punch column 123. The punch column 123 moves with the upper die base 12 and slides coaxially through the support punch tube 113. On the one hand, it can support the integrated copper terminal, making the punch column 123 punch more smoothly and reducing the deformation of the copper terminal. On the other hand, the waste generated during the punching process can also fall out along the lower opening of the support punch tube 113, avoiding the accumulation of waste and facilitating continuous operation.
[0041] Two sets of drive cylinders 124 for vertically moving drive pins 123 are fixed inside the upper mold base 12 by bolts. The peripheral ends of the pins 123 are provided with grinding grooves 1231. The pins 123 slide into the support punch tube 113 and grind the inner wall of the opening of the copper terminal. This makes the punching of the pins 123 and the cutting of the cutting head 121 asynchronous. When the integrated copper terminal slides into the cutting groove 111, it is punched first and then cut. This allows the formed copper terminal to automatically slide from the support punch tube 113 into the unloading groove 112, which is more convenient. At the same time, the grinding grooves 1231 on the peripheral ends of the pins 123 allow the inner wall of the opening to be ground to a certain extent after the pins 123 punches. This reduces the subsequent processing steps of the copper terminal and makes it more convenient. It also reduces the impact on the copper terminal during the retraction of the pins 123.
[0042] Separation screens 114 are fixed on both sides of the lower die base 11 below the opening at the lower end of the feeding chute 112. The separation screens 114 separate and screen copper terminals and copper terminal hole waste. The separation screens 114 can separate copper terminals and waste generated from punching, thus facilitating the subsequent removal of copper terminals.
[0043] The conveying assembly 2 includes a feeding slide 21 and baffles 22 disposed on the feeding slide 21. The feeding slide 21 is fixed to the lower die base 11 along a length direction perpendicular to the cutting slot 111. The feeding slide 21 is inclined and allows the integrated copper terminals to slide down sequentially. The lowest end of the feeding slide 21 is connected to the cutting slot 111. The baffles 22 slide vertically and are connected to the bottom wall of the feeding slide 21 at the end connected to the cutting slot 111, intercepting the integrated copper terminals. Two sets of baffles 22 are provided, and the two sets of baffles 22 are spaced apart along the opening direction of the feeding slide 21, forming a gap between the two sets of baffles 22 for one set of integrated copper terminals to stay. The integrated copper terminals slide down the feeding slide 21 sequentially for feeding. The gap between the two sets of baffles 22 allows only one set of integrated copper terminals to stay, thus ensuring that only one set of integrated copper terminals is allowed to slide into the cutting slot 111 each time, avoiding cutting errors caused by excess integrated copper terminals sliding in.
[0044] The lower die base 11 has a waste material slide 115 on the side wall of the cutting slot 111 away from the loading slide 21. The waste material slide 115 is inclined and connected to one side of the lower die base 11. The waste material cut by the cutting head 121 slides into the waste material slide 115 under the pressure of the next set of integrated copper terminals, so that the waste material is automatically cleaned after each stamping and cutting, which is more convenient and improves production efficiency.
